13 Claims. 1

This invention relates to new and useful improvements in pile fabrics such as rugs and carpets.

Among the objects of the invention is to provide a pile fabric with ground and figures respectively constructed from pile of different heights interrelated in such manner as to provide distinctive and unique texture effects due to the different heights of pile, the quantity of yarn which forms different individual pile, and various arrangements of discontinuous rows of pile of one or another height. I

Another object of the invention is to provide a pile fabric wherein pile or tufts of different heights are selectively located to form figures and ground and some of the pile or tufts are selectively influenced to lean in one or another direction warpwise of the fabric to provide curvilinear effects in different rows of pile fastened to the fabric between straight rows of weft shots, whereby unique designs with a variety of curvilinear and linear rows of pile are produced in either the figures or the ground or in both the figures and ground.

Another object of the invention is to produce a pile fabric having certain selected pile yarns raised above ground pile and definitely producing elevated design areas within which the higher pile is variously inclined from the root of the pile so that pile in rows of pile which are attached in straight rows weftwise of the fabric are inclined at various angles from the vertical in the warpwise direction of the fabric and curvilinear effects are produced in the elevated designs.

Another object of the invention is to provide a method for making a pile fabric wherein pile of different heights are arrangeable to form figures in relief rising from the groun of the fabric and merging therewith in a hill-and-dale manner. The relief may have a limitless variety of forms with higher pile thereof constituting the visible aspects of the .relief while some of the lower pile remain hidden but contribute to influence the form of the relief portion of the fabric by giving lateral support to the higher pile on one side or the other, while other of the lower pile is visible in lower portions of the relief and is a part of the structure of the ground about the more elevated relief portions of the fabric.

Another object of the invention is to provide pile fabric wherein pile is formed by looping warp yarn ends over a series of straight wires of varying heights to form rows of pile of varying heights confined at their bases in straight lines between adjacent weft shots, and the wires are 2 so arranged and warp yarn ends are so selected as to cause relocation of the tops of the higher pile out of alignment with their bases by the omission of pile at one side of high pile and the application of support against their opposite side which is provided by the presence of adjacent pile of the same or lower height. The relocation of the tops of the higher pile may effect, as desired, a curvilinear appearance in the surface of a finished pile fabric, as observed from above, notwithstanding that all of the pile-forming wires which are used in fabricating the fabric and forming the pile are straight. The ornamentation thereby produced results in permanent texture throughout the fabric which is retained even though the fabric and the pile is subjected to pressure during use. The lower pile supports the higher pile and causes restoration of the higher pile after crushing. A further and important achievement of the invention is the saving in warp yarn that can be accomplished without leaving any portion of the carcass of the fabric uncovered.

The principle of the invention is capable of utilization for the making of Wilton carpet fabrics, velvet carpet fabrics, plush and velvet upholstery fabrics and Brussels carpets. The pile or tufts may be cut or uncut throughout the fabric or may be selectively cut or uncut in a single fabric to provide contrasting areas of pile, depending upon which of the pile wires have cutter blades.

The process employs straight pile wires of different heights or widths and effects the control of the placing of yarn thereover for producing piles of different heights, and also the omission of pile between weft shots. The fabric can' be made on a standard loom which is prepared by the insertion of pile wires which are selected and arranged in such sequence as is required to'produce a desired arrangement of high and low pile in the finished fabric.

The selection of the warp yarn ends for forming pile or for running warp yarn ends in the back or base of the fabric .is predetermined by the'Jacqu'ard cards upon which the desired Dattern has been placed. By reason of the control effected by the cards and the arrangement of the various wires in the wire box of the loomfthe warp yarn ends are selected to locate and to produce pile of different heights and also to omit pile between selected weft shots. The number of different heights of wires is variable according to choice to provide whatever undulating or other efiect is desired to be obtained by the pile of the fabric. The pile may be of three, four, five or more heights, according to choice, with the wires arranged in a variety of sequential combinations, giving regular or irregular effects, as desired. For explaining the principle of the invention, I have selected for illustration a fabric which was produced by the use of pile wires of four different heights. I wish it to be understood, however, that the utility of the invention is not limited to any particular pattern, figure, texture or the choice of colors of the various warp yarns when color effects are desired.

Referring to the drawings,

Fig. 2 is a card-cutting guide for producing the design of the pile fabric illustrated in Fig. 1;

Fig. 3 is an isometric view of the pile fabric illustrated in Fig. 1;

Fig. 4 is a sectional view of pile wires as arranged for looping yarn to form pile of different heights to produce the fabric illustrated. In this view the warp yarn end in course A is shown looped over certain of the wires;

Fig. 5 is a section warpwise of the fabric illustrating the pile in dents or courses A, B and C of the pile fabric illustrated in Fig. 1: and

Fi s. 7, 8. 12. 13 and 14 show, respectively, warpwise sections in dents or courses D, E, F, G, H I, J, K and L of the pile fabric illustrated in Fig. 1.

The carcass or back of the pile fabric is of conventional type. Asshown in the warpwise section illustrated in Fig. 3, the carcass includes two chain or binder warps I, 2, interlacing alternately after passing over and under the top and bottom shots of filling 3 and 4, respectively. The usual stufi'er threads 5, 8, and warp yarn ends I, 8 and s are located between the upper and lower weft shots, as is common in a Wilton-type of pile fabric. The warp yarn ends which are not selected to form a tuft or pile on the face of the fabric remain in the back of the fabric. For the purpose of illustrating the invention, I have shown one warp yarn in each course looped over the pile wires for forming all of the pile in one course of the fabric, but it will be understood that when designs employing diiferent colors are desired, colored warp yarns are selectively looped as desired over the pile wires or floated in the back of the fabric in accordance with a predetermined pattern of selection. Consequently, there may be a number of warp yarn ends in each course 4 The area of the fabric immediately surrounding the diamond-shaped elevated area is made up in the present example of fabric of rows of pile or dent. I have illustrated several warp yarn ends, although for the purpose of understanding my invention it will suffice .to describe-a pile fabric whereinonly one of the warp yarn ends enters into forming pile.

The fabric illustrated in Figs. 1 and 3 has a diamond-shaped elevated design area which is formed from nine rows of yarn which has been selectively looped over high wires. These rows run weftwise of the fabric and vary innumber of pile, the first row having two pile, the second row having six pile, the third row having 12 pile, the fourth row having 18 pile, the fifth or middle row having 24 pile, the sixth row having 18 pile, the seventh row having 12 pile, the eighth row having six pile, and the ninth row having two pile. All of these high looped pil'e are visible but the same elevated design area includes a number of low pile which are not visible from above but nevertheless enter into forming the configurations which the line's of high pile have, as will be explained hereinafter.

of three different heights, the highest of which is of less height than the highest pile in the elevated design area. The rows of pile runing weftwise of the fabric may be straight or curved, as desired, and the amount of curvature is variable, depending upon the placement and height of adiacent pile in the same course and the presence or absence of voids in the face of the fabric. It will be appreciated that by selectively raising pile of different heights the amount of curvature in any one row of pile weftwise of the fabric may be varied to produce different textures.

For producing texture in both the elevated design and in the ground of the fabric illustrated in Fig. 1, the pile wires are assembled in the wire box of the loom in a given sequence, but other textures may be eflected by a, diiferent sequence and by the use of a different number of wires of different heights. The sequence of the wires by which the fabric illustrated in the drawings is produced is indicated in Fig. 2 by the numerals i, 3, 2, l; I, I, 2, 4, etc., starting from the left edge of the card-cutting guide. The values of these numerals designate the relative heights of the wires, and their relationship indicates the sequence of the wires assembled in the wire box of the loom. The numerals indicating the relative heights of the wires are herein designated for convenience, as followsgthe low wire, one-high; the second highest wire, two-high; the third highest wire, three-high; and the fourth highest wire, fourhigh. The relationship of these wires is illustrated in Fig. 4. With four heights of wires being employed a wire box containing 28 wires would have a series of four wires repeated seven times.

The function of the Jacquard card is to raise and leave unraised certain yarn ends to produce pile in the surface of the fabric in the usual manner of operation of Jacquard mechanism, but the selection of the yarn ends is predetermined and set into the design of the card to obtain the novel pile fabric of the present invention. This involves the location of pile of low height with respect to pile of higher height in adjacent rows and the selective forming of voids. By. selectively raising the warp yarn ends in different rows crosswise or weftwise of the fabric, the high Pile in any one row can be variously inclined warpwise and it can be differentially inclined to provide a of rows l5, l8 and I1, i8 with each pair of rows being of less length as the design of the diamond approaches the apices at either side. The two pile 19 at the left apex and the two pile 20 at the right apex of the elevated design are inclined equally to the left.

The approximate inclination of any particular pile or tuft in each of the courses A to L, inclusive, is schematically illustrated in Figs. 5 to 14, inclusive. The first three courses are identical and are illustrated in Fig. 5, each having a first pile 2i one-high in the first row, a threehigh pile 22 in the second row and the warp yarn floating at 23 and 24 in the back of the fabric in the third and fourth row. The next two pile wires form a. one-high pile 25 and a three-high pile 26, but the yarn was left unraised in rows 21 and 28. The effect of having pile 2| and 25 immediately to the left of the higher pile 22 and 26, respectively, and omission of pile in the two rows immediately to the right of the higher pile 22 and 26 is to cause the higer pile 22 and 26 to incline to the right or in the direction of least support. The warp yarn of the pile illustrated in Fig. is shown as looped over pile wires in Fig. 4. When this is done in the loom the yarn is under tension, but when the wires are withdrawn the pile yarn opens up somewhat as illustrated in Fig. 5 except where bound at the root.

In the fourth debt which is identified as D and illustrated in Fig.6 there is no pile raised between the first pair of weft shots and therefore there is an omission of pile at 29. The pile is raised in the second row over the three-high wire and forms a three-high pile '30. In the third and fourth rows 3| and 32 the yarn is floated in the back of the fabric, but in the fifth row the yarn is raised over the one-high wire to form a pile 33. A three-high pile 34 is formed in the sixth row but the yarn end is floated in the back of the fabric in rows 35 and 36. It will be seen that by comparing the pile structure in Figs. 5 and 6, the three-high pile in the second row is inclined differently in the two courses, the pile 22 in courses A, B and C being inclined to the right, and the pile 30 in course D being equally unsupported on both sides and having the tendency to remain erect or vertical.

In course E, as illustrated in Fig. 7, pile 31 in the second row of the fabric is given support on its right side by a two-high pile 38, with the result that pile 3'| tends'to incline toward the left. Inclination of pile 31 to the left is greater than the inclination of pile 22 to the right because the immediately adjacent pile 38 is higher than the immediately adjacent pile 2| and therefore provides greatersupport than the lower pile.

It will be appreciated from the description thus far set forth that the second row of pile from the left will be given a curving appearance when viewed from above (Figs. 1 and 3) because of the inclination of the pile to the right in the first two courses A, B and C and the inclination of the pile to the left in courses E, F, G, H and I. This produces a curving effect as illustrated in Fig. 1 by the dotted line 39.

The pile just described is located in the area of the fabric which is designated as the ground area. In this area the highest pile is of less height than the highest pile in the elevated area and because of this there will be more of the.

lower pile showing in the ground area. In other words, the ground area is constituted of pile of three different heights with a, large proportion of the shorter or one-high pile showing in the surface of the ground, It will be appreciated that the amount of curvature or the lack of curvature or the presence of lineal texture in the ground can be variously effected, depending upon the location of the pile of different height in adjacent rows weftwise of the fabric and the number of pile and omissions of pile in the various rows. For example, the warp yarn ends in the first six courses starting from the bottom of Fig. 1 are raised over a two-high wire in the eleventh weftwise row from the left, as illustrated in Figs. 4 to 8, inclusive, and on either side of this row of six pile there are omissions of yarn between adcontacting proximity with the immediately adlacent four-high pile 41 and 48, respectively. It therefore follows that arow of pile emanating from a straight root can be given the appearance of lying in a straight line or in a curved line, as viewed from above, and that a single row of pile may be made to appear curved or straight, depending upon the presence and absence of pile in adjacent rows.

As an example showing the manner in which a reverse curve effect can be produced in a single row of pile weftwise of the fabric, reference may be had to the central row 0 of the pile contained in the diamond-shaped design located centrally of Fig. 1. In the first three courses, A, B and C, Fig. 5, the four-high pile 50, Fig. 5, is biased to the right because of the strong support given by the two-high pile 5| at its left side. In the same row but in course D, Fig. 6, pile 52 is influenced to the right but to a lesser degree than pile 50. This is because pile 53 provides less pressure on the left side of pile 52 than is provided by pile 5| on the left side of pile 50. In the next two courses, Figs. 7 and 8, pile 54 and pile 55 have substantially the same amount of influence to the right as pile 52 in course D. In course G, Fig. 9, pile 56 is substantially vertical because the next two piles to the left and right are equispaced and exert substantially the same pressure on either side of pile 56. In course H, Fig. 10, pile 51 is inclined slightly to the left because of the presence of a one-high pile 59 immediately adjacent its right side. In course I, Fig. 11, pile 59 has a greater inclination to the left because of the presence of the one-high pile 60 at its right side and the leftward inclination of pile 5| which is brought about by the presence of 'a one-high pile 62 at its immediate right side.

Pile 63 is also influenced to the left because of its proximity to pile 59, but less so than pile 59 because of the absence of pile in row 64 which, if present, would apply lateral pressure against pile 63 in the manner in which lateral pressure is applied against pile 59 by pile 60. In course J, Fig. 12, pile 65 which is in the same row of pile as pile 63, has immediately adjacent its right side a one-high pile 56, with the result that pile 65 has more force applied against its right side than pile 63 has. Consequently, pile 65 is inclined to the left a greater degree than pile 63. In course K, Fig. 13, each of piles 61, 58, 69, I0 and II has a lower pile in the row immediately adjacent its right side, so that all of these five pile are more strongly urged to incline to the left than the five pile in the same rows in course J, Fig. 12. The influence to incline to the left of all of the high pile in course L, Fig. 14, is a little greater because each of these nine fourhigh pile has a lower pile immediately to its right which tends to support the pile at their right side. This may be appreciated by comparing pile 12 in course K, Fig. 13, and pile 13 in course L. Fig. 14, the latter being partially supported at its right side by a low pile 14 and the former pile I2 tending to remain a little more Y 7 upright because of the absence of low pile in row 15 and its natural tendency to remain upright except forthe opposition provided by pile.

Consequently, pile 12 6'! in the same course. extends at an angle to the vertical of lesser degree than the angle which pile 13 makes to the vertical. The effect of this construction may be cline in one or another direction warpwise of the fabric in varying degrees in different courses can be employed throughout the elevated design and throughout the ground, or in portions of the elevated design and portions of the ground, as desired. By varying the locations of the pile in the surface of the fabric, different curvatures may be produced with resulting varieties of texture.

By inspecting Fig. 1 it will be observed that pile 56 in course G lies centrally with respect to the straight line H which delineates the center of the root of the weftwise row of pile, and that the pile in the same row in courses H, I, J, K and L are inclined differentially towards the left, whereas, the pile in the same row in courses A, B, C, D and F are likewise inclined, but to the right.

The visible aspects of the diamond design are produced by the four-high pile within the diamond area, and consequently this area is elevated above the surrounding ground. Within this area the low pile, such as the one-high pile 58, 60, 62, 66 and H normally are invisible from above. but their presence is required in order to produce the curvilinear effects just described.

In Fig. 2 I have shown a diagram of the design shown in Figs. 1 and 3, such as is used for the card cutters guidance in transferring a design onto Jacquard cards by which the yarn ends are controlled for producing the design.

The vertical rows are marked to correspond with the arrangement of the pile wires previously set into the wire box of the loom, which arrangemerit in the present case, is I, 3, 2, 4; l, 3, 2, 4, etc. The yarn ends in the several courses or dents are marked along the vertical edge of the card-cutting guide by letters A to L, inclusive. Since the elevated design is symmetrical on a longitudinal axis, X-X, the Jacquard pattern above the axis X-X will correspond with pattern below the axis but in descending series, that is L to A, inclusive, within the elevated design area. The clear areas correspond to the location of pile and the blackened areas correspond to absence of pile. The vertical axis Y-Y corresponds to the straight row of pile roots indicated by line H in Fig. 1. It is to be understood that symmetry of design is not essential and that the fabric can be characterized by irregularity of pattern. This can be understood by studying the ground area outside of the diamond marked on Fig. 2, wherein it appears that all of the weftwise rows of pile are not symmetrical about axis X--X. By comparing -the diagram with the illustrated designs of the fabric, it will be immediately apparent how the particular card selects the warp yarn ends in the various dents to loop the yarn ends over the several wires or to leave the yarn ends floating in the back of the fabric to provide omissions of yarn as each row of the fabric is constructed. As a consequence of forming the pile of the fabric just described at no time is any one of the pile wires fully covered with warp yarn ends, yet no part of the carcass or back of the'fabric can be seen when the pile is normally disposed as when the fabric is in use.

The yarn ends which are selected to form pile are tightly held at their bases by pairs of weft shots. Since the piles are of different heights the yarn in the higher piles will tend to assume relatively larger diameters than the yarn in the shorter piles when the pile-forming wires are withdrawn. These difierences in the diameters of the yarns of the several pile are somewhat exaggerated in the drawings for the purpose of illustrating the relative differences and the effects which the various pile have in producing different texture in different parts of the over-all pattern of a rug. The higher pile tends to diffuse laterally more than the shorter pile.

In the pile fabric which has been selected for the purpose of explaining the principle of the invention, pile wires of four different heights are used for producing pile of four different heights, but it is to be understood that a more or less number of wires may be employed and that their arrangement with respect to each other may vary for producing different pile fabrics. The utility of the invention is not limited to any particular pattern, figure, texture,-or to choice of colors of the various warp yarns when color effects are desired. In the rug illustrated the high lights and shadows are different as the rug is viewed from the left or from the right and this effect is variable according to the selection ofpile wires and their sequence.
